CntSetTestPulse

Function

Executes the output setting of test pulse.

Format

Ret = CntSetTestPulse ( Id , Internal , Out , Reserved )

Parameters

Id [ C, C++ : short] [Python: ctypes.c_short]
Specifies the device ID retrieved from CntInit.

Internal [ C, C++ : short] [Python: ctypes.c_short]
Change the output destination of test pulse.
0: External
1: Internal

The following devices are equipped with the test pulse function.
For more information about the test pulse function, see the "Remarks" item.

Model Number	External	Internal
CNT-3204MT-LPE CNT-3208M-PE CNT32-4MT(LPCI) CNT32-8M(PCI)	OK	OK
CNT-3204IN-ETH CNT-3204IN-USB	N/A	OK

Out [ C, C++ : short] [Python: ctypes.c_short]
Specify the output in ON or OFF.
0: OFF
1: ON

Reserved [ C, C++ : int] [Python: ctypes.c_int]
Specify 0.

Return Value

Ret [ C, C++ : long] [Python: ctypes.c_long]]

Definition	Value	Description
CNT_ERR_SUCCESS	0	Normal Complete
CNT_ERR_DLL_INVALID_ID	10001	Invalid ID is specified.
CNT_ERR_DLL_CALL_DRIVER	10002	Driver cannot be called (failed in ioctl).
CNT_ERR_SYS_MODE	20100	Invalid mode setting.

Remarks

The output frequency is fixed in 100kHz. Outputs 2-phase pulse to all channels.

Please select the output destination of the test pulse according to the application.

the output destination of the test pulse

Definition

External

When the test pulse output is set, the signal is output to the outside.

By using this function, it is possible to identify whether there is a defect in the encoder, cable, or encoder input circuit.
It may help to identify the defective part.

Internal

When the test pulse output is set, the count value increases.

Operation of the application software can be checked without signal connection.

Example

C, C++	Ret = CntSetTestPulse (Id, 1, 1, 0);
Python	Ret = ccnt.CntSetTestPulse (Id, 1, 1, 0)
